How do your two selected body systems interact with one another to help the human body function
efficiently
Answer:Some body systems work together to complete a job. For example, the respiratory and circulatory systems work together to provide the body with oxygen and to rid the body of carbon dioxide. The lungs provide a place where oxygen can reach the blood and carbon dioxide can be removed from it.

13. A group of students want to investigate the effects of plant moisture on the growth of caterpillars. The
students fill three identical boxes with an equal number of a kind of leaf that caterpillars eat. The students
keep the leaves in the first box dry, spray the leaves in the second box with two sprays of water, and spray
the leaves in the third box with four sprays of water. The students then add four caterpillars to each box.
Every day the length of each caterpillar is measured and recorded, and the results are averaged. What is
the outcome/dependent variable in this experiment?
A. The number of leaves put in each box
B. The amount of water put on the leaves
C. The number of caterpillars in each box
D. The change in length of the caterpillars.
The outcome or dependent variable in this experiment is the change in length of the caterpillars, which is option D. As the students are investigating the effects of plant moisture on the growth of caterpillars, the growth of the caterpillars is the variable that they are measuring.
What are variables?In an experiment, there are two types of variables: independent variables and dependent variables. Independent variables are the factors that are manipulated or changed by the researcher, while dependent variables are the factors that are measured or observed in response to the changes in the independent variables. In the given experiment, the independent variable is the level of moisture applied to the leaves, which is varied across the three boxes. The dependent variable is the change in length of the caterpillars over time, which is measured and recorded every day.
Hence, the outcome or dependent variable in this experiment is the change in length of the caterpillars, which is in option D.

Explanation:
[tex]\sf{ }[/tex]
The capsid copies the host cell’s DNA is the role of the capsid play in viral reproduction.
The role capsid play in viral reproduction is that the capsid copies the host cell’s DNA. Thus, option C is correct.
What is reproduction?
Reproduction has been defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction has been the supreme quality of living things. The role capsid play in viral reproduction is that the capsid copies the host cell’s DNA.
There are two types of reproduction and these are sexual and asexual reproduction. The process of reproduction in which two parents are involved has been said to be sexual mode of reproduction and the process of reproduction in which only single parent has involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.
Therefore, The role capsid play in viral reproduction is that the capsid copies the host cell’s DNA. Thus, option C is correct.

On the Galapagos Islands, in the Pacific Ocean, live over a dozen species of small birds that are the same except for their beaks. Each species beak is a different size and shape. Birds with small, narrow beals ate either small seeds or insects. Birds with large beaks ate larger seeds. Based on the information in the passage, explain why there are two different beak sizes on the island. What will most likely happen to the finch population if the large seed plant becomes extinct.
Why would this happen? How can adaptations and natural selection help explain the reasoning for population changes in finches?
Answer:If the large seed plant becomes extinct the finches with larger beaks will probably die out thus reducing the finch population
2)This will happen as their source of food is gone and thus leaving them to either feed on what there not used to or die
3)im not too sure of this but this is what i think; In Darwin's finches, those that have short beaks turned out to be an adaptation that made them more suited into poking holes in the ground and feed on grubs. Also the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.

Which of the following is not typically represented by pyramids in ecology? 30 points
- mass, - energy flow, - populations in ecology, - predator and prey relationships
The biomass pyramid shows the decline or steady decline in biomass from base to peak of each trophic level. Pyramids employed in ecological systems don't use fresh weight.
What is the role of biomass in ecological pyramids?The biomass that is produced by organisms at every trophic level can be measured using a biomass pyramid.
The bottom level of this pyramid is occupied by the producer, which are typically plants. Primary consumers come after the producers.
The total living biomass or organic matter present at various trophic levels in an ecosystem is represented by a biomass pyramid.
The mass of living things present at each trophic level in a given sample size is used to determine biomass. Calories per unit area or dry weight in grams are two ways to see it.
Therefore, biomass is not typically represented by pyramids in ecology.

Answer:
Plant Guidance by Ecoregions
Ecoregion 9 – High Plains
Extending from the Panhandle south to the Pecos River, the High Plains have been described as a sea of waving grasslands. The 20 million acres of this region fills most of the “handle portion” of the state. It is a relatively high and level plateau of sandy to heavy, dark calcareous clay soils over an impervious layer of caliche. The winters here are the coldest in Texas, with the average annual temperature being only 59 degrees. Rainfall ranges from 21 inches in the east to about 12 inches in the west. Sun and wind rob the soil of even the meager water it receives from these rainfalls. Today, most of the High Plains is irrigated by the vast Ogallala formation.
Classified as mixed plain and short-grass prairie, vegetation in the High Plains varies – highly dependent on location. Hardlands or mixed lands, sandy lands or caliche lakes, all give rise to a very different plant community. Honey mesquite and yucca have invaded some areas that were characteristically free of trees and brush. Sand sage and shinnery oak have spread through most of the sandy lands.
Playa lakes play an essential role in this region, and they are the prime waterfowl wintering grounds for the North American Central Flyway.
The regions other name, “Llano Estacado” or “Staked Plains” is believed to refer to the first European settlers who drove stakes into the ground to help guide them across this featureless region. These early pioneers found a vast carpet of short grasses that were home to enormous herds of buffalo and pronghorn antelope. This was also the home of the Comanches.
The original character of the High Plains has been forever changed by the plow, however unique areas still remain including some scattered sand dunes cloaked with Harvard shin-oak, sandsage, and little bluestem. Tallgrass meadows can still be found waving in the breezes along the Canadian and Red Rivers. While few rivers actually cross the High Plains, these meager water sources along the Canadian and Red Rivers one sustained luxuriant growths of tall willows and cottonwoods. Russian olive and tamarisk, two introduced species from the Old World, now replace these native trees along the rivers, altering the natural habitat of kingbirds and phoebes. Grasses still provide cover and nesting habitats for myriads of other birds, and belts of trees planted in the 1930s provide shelter to an amazing diversity of wildlife. While the Gray Wolf and elk no longer occur on the High Plains, mountain lions, coyote, Red-tailed Hawk and swift fox now crown the food chain. While greatly reduced, scattered populations of Lesser Prairie-chicken still boom to announce the coming of spring across the region while flocks of Lark Buntings and Horned Larks ply the skies over this restless sea of grass.
